About This Product
A cut shoot is sealed into the stopper, the whole apparatus is filled with water and the open end of the capillary is placed in a beaker of water. Rates of transpiration and absorption can then be compared as the conditions around the shoot are changed. Opening the stopcock lets water in from the reservoir to bring the air bubble back to a convenient position.
